Chelsea legend Frank Lampard has told talkSPORT the club needs to make more signings this summer if they are to compete on all four fronts.

The 2016/17 Premier League champions have added Alvaro Morata, Tiemoue Bakayoko, Antonio Rudiger, and Willy Caballero this summer, but sold stars like Nemanja Matic, Nathan Ake, Asmir Begovic, and Nathaniel Chalobah, leaving them, on paper, no stronger than before.

And with the Blues competing in the Champions League again thanks to last season’s success, Lampard insisted more players will be needed for the battles ahead.

“I think you can sense a frustration in Antonio Conte’s press conferences and I can kind of understand that,” he told the Weekend Sports Breakfast.

“If you have such a good season as they did last year, as a manager and as a club you want to push on and freshen up the team, and adding to it is important. Particularly if you’re losing some big players and Diego Costa seems to be [on] the way [out] but I don’t have too many worries about that. Alvaro Morata will be a good signing. I think he’s going to be a 20-goal a season man.”

“What I do think is they need to strengthen as they’re in the Champions League this season and you need a really strong squad. They need to add to it.”

Meanwhile, the Stamford Bridge hero also believes the club must do all they can to hang onto their prized assets.

“It’s hugely important they keep Eden Hazard,” he added. “For me he is one of the best players in the Premier League and in world football. When he is fit and playing he makes Chelsea the team they are.”
